The "some improvements" update

Hello!

I added some improvements to the app like

• Fixed image sizing on reader
• Slight UI Tweaks
• Barebones Settings Menu
• Open with Fictie
• Open by ID
• Reader Light/Dark mode toggle

Hope you'll enjoy it! Feel free to open an issue for feature recommendations or bugs, or contribute by creating a PR!
